  • US 2010/0169185 describes such a method in which users use a web-based program to create and edit a three- dimensional model before exporting the completed model file to an off-site rapid-prototyping location for production and shipping of the physical object.

Some embodiments of the invention also provide ways for multiple users to create collaborative personalized objects.
  • such a method for creating personalized objects having mechanically functional portions comprises a step of editing a three-dimensional model using a computer program and a step of transforming the model into a physical object using a rapid prototyping machine, is characterized in that during the editing step:
  • a computer program processes a deformation of the original model into a deformed model
  • a three-dimensional geometrical constraints database associated with said models, provides a set of constraints on the geometry of said mechanically functional portions
  • a computer program computes at least one step of comparison between some geometrical constraints from said database and a model selected between the original model and the deformed model.
  • users can personalize the object by deforming its shape while geometrical constraints ensure that the final physical object will be able to perform its designated mechanical function.
  • the constraints database can comprises one or a combination of the following constraints :
  • At least one step of comparison is followed by the step of sending the user a warning message if at least one of the constraints is not fulfilled by the model.
  • At least one step of comparison is followed, if at least one of the constraints is not fulfilled by the model, by the step of correcting said model to fulfill the set of constraints.

  • Figure 2 shows an original model of a functional object intended to be personalized together with an associated three-dimensional constraint mesh and a model of another object
  • Figure 3 is an organizational flow diagram of the editing step.
  • the steps of making a personalized functional object 1 first comprises a step 100 which consists for users in retrieving an original three- dimensional model 10 of the object 1 they intend to create, as well as a geometrical constraint database 30 associated with said model 10.
  • the object 1 is a functional object, meaning that it has at least one mechanically functional portion la whose geometry in the final physical object 12 should respect some constraints if object 1 is to perform its designed function.
  • users edit the model 10 by deforming its shape to obtain a deformed model 11. They can also change its color, texture as well as other parameters in order to freely personalize it.
  • a final step 300 consists in the creation of the physical object 12.
  • a rapid-prototyping machine constructs the object 12 by interpreting deformed model 11.
  • a single user can perform the editing step, on a stand-alone software or through a web-browser or a web interface.
  • a second embodiment of the invention several users can edit the same model at the same time or at different times, on a stand-alone software or through a web-browser or a web interface, thus allowing for collaborative edition and creation of the personalized object .

  • the portion la for example has the shape of a cylinder on the original model 10 and is intended to be inserted in a mating hole 2a of the object 2.
  • Object 1 also comprises a freely customizable portion lb whose shape can be deformed at will by users without affecting the mechanical function of the object 1.
  • the portion lb On the original model 10, the portion lb has the shape of a cube located at one end of the cylinder la.

  • the object 2 consists in a cube having a cylindrical hole 2a.

This mesh indicates regions of the physical object 12 that should be empty of matter in order for the portion la to perform its mechanical function: being inserted in the hole 2a of object 2.
  • other meshes 3 can be located for example inside the portion la, to define regions of the physical object 12 that should be full of matter or contain at least a determined quantity of matter for the portion la to be functional. This determined quantity of matter can be for example needed to keep the portion la sufficiently rigid.
  • Constraints from the constraints database 30 associated with a model 10 may therefore comprise three different types of regions:
  • constraints may not be superimposed to the model on screen, to improve visibility .

  • a database 6 of models from which the model 10 can be selected, as well as the database 30 of constraints associated to the model can be uploaded on the computer via the web.

  • a computer program 60 performs a step of comparison 220 between the deformed model 11 and a set of geometrical constraints 3 from the database 30. If the result of this comparison is that some of the constraints 3 are not satisfied by the deformed model 11, a step 230 of correcting the model is accomplished. This step 230 can comprise adding or withdrawing matter to model 11 in order to satisfy the set of constraints 3.
  • the step of comparison 220 can be followed by a step 240 of sending the user a warning or error message instead, or during step 210, through window 9.
  • the warning message can be a visual message such as a warning or error box, a modification of the visual aspect of the model or a modification in the interaction permitted between a user and the model. In a variant, it can be a sound message.
  • the step of comparison 220 is accomplished several times during the step 210, for example on a timely interval, after each of users' deformation of the model or only after some specific deformations of the model.
  • the original model 10 can itself be not functional, meaning that it does not satisfy the set of constraints 3.
  • the application of step 220 and following steps 230 or 240 is essential to ensure that the final physical object 12 is functional .
  • the portion lb can also be considered functional, as it can be actuated by a user to open a door. Constraints defining this function can also be used.
